My mother has fibroid, gynecologist suggested removal of vagina, need second opinion?

Sir, my mother has fibroid from 2-3 years ,from 24 th feb she started bleeding and bleeding continued for 10 days due to which her haemoglobin level decreased to 4.4 , she once fainted due to such low haemoglobin so we took her to gynecologist and she immediately advice blood transfusion (4 units of blood in span of 26 hr)
Now after transfusion her haemoglobin level is 9.2
I have 2 question
Firstly i will tell you she is in completely bed rest at home from 2 days now i.e no work no walking (she used to do evening walk of 1/2 hour) no exersise and yoga.
1. After blood transfusion she is normal (apart from weekness) , doctor also gave medicine and injection to stop bleeding
Now question is she started drinking water all time after blood transfusion i.e 2 litre during night time from 10 pm to 6 am. Is this normal (nothing strange apart from this )

2.related to fibroid, what should we do next , gynecologist at 2015 suggested removal of vagina ,but my mother is afraid of doing so , hence we moved to ayurvedic doctor who gave medicine now fibroid size is reduced to 1/4 th (i think 1/2 mm now), but bleeding is getting worse as time passing -should we continue ayurved or do the operation.
